The attack is being investigated as a possible hate crime and Chicago police are searching for the men involved.
Donald Trump has called the attack on Empire star Jussie Smollett “horrible” and condemned the assault by two men who allegedly referenced the US president’s “MAGA” campaign slogan as they assaulted him.
Two days before, a letter containing a white powder and homophobic message referencing Smollett was sent to the Empire set.
Smollett, who is black and came out as gay in 2015, was attacked in Chicago just after 2.30am on Tuesday (29 January).
